APPARATUS FOR PASTING SHEETS INBINDING BOOKS.

SPECIFICATION forming part of Letters Patent No. 276,224, dated April 24, 1883.

Application filed October 2, 1882.

T 0 all whom t't may concern:

Be it known that we, GALEN CARLTON, of Brooklyn, ELI) in the county of Kings and State of New Yorlt,and DAVID M. SMYTH,

of Hartford, in the State of Connecticut, have invented an Improvement in Apparatus for Pasting, Gumrning, or Tipping Folded Sheets in Binding Books, of which the following is a specification.

In binding books it is usual to paste the end sheets to the first and last signatures. In sewing books by such machinery as that shown in patents heretofore granted to David M. Smyth, the paste upon the end sheets is liapresser, and

come off upon subsequent sheets.

The object of thisinvention is to apply a line of paste or other adhesive material in the proper place for cementing the signature and sheets together without risk of the paste spreading, and to do this with great rapidity and accuracy.

In the drawings, Figure 1 is an elevation of the apparatus, partially in section. Fig. 2

is a cross-section at the line 00 00,- Fig. 3

shows the edge of the paste-roller in larger size; Fig. 4 is an elevation of the apparatus with the paste-box below the fixed cover and ready to be moved up and attached to said cover, and Fig. 5 is a partial plan view of the cover and the blade upon thepaste-box.

The box A is adapted to hold the proper quantity of paste or other adhesive material.

It is removable from below the cover B, which usually will be fastened by brackets 0 from some suitable part of the book-sewing machine.

The paste-box A and cover Bare connected in any usual manner. We prefer to employ a blade of sheet metal, (I, that passes up into 40 a slot in the cover B, and books 6 pass below a flange at one end of the box. There is a hook,f, depending from the cover B and passin g in between flanges h at the end of the box,

and these flanges are perforated, sothat a pin can be inserted through the flanges and above the hook to connect the box to the cover after the other end of the box has been secured by the blade (I and hooks 6. This construc- (No model.)

tiou allows for removing the box and pastewheel for cleaning the same.

The paste-wheel k is narrow and provided with a groove in its periphery, which, becoming filled with paste, places a line of paste upon the paper, near to and parallel with the back or folded edge of the sheet or signature. The surfaces of the wheel are preferably milled, so that the wheel will be revolved by the paper as it is drawn along over the edge of this wheel. 1 t

The shaft Z of the paste-wheel k is in jouruals at the sides of the box A, there being slide-caps that fill the notches in the sides above the journals. These allow the shaft and roller to be lifted for cleaning. The scraper m is fastened to the box, and it is slotted for 6 the paste-wheel, and it is movable, so as to set closer to or farther from the edge of the wheel and regulate the quantity of paste.

In the cover B is a slot for the paste-wheel to project up through, and upon the cover is a movable gage, n, that can be adjusted to regulate the distance between the line of paste and the folded edge of the sheet, which sheet is drawn over the wheel 70, with the fold against the gage at. There is a yielding press- 7 er to keep the sheet down upon the pastewheel. For this presser we use a roller, 1), that is upon a gudgeon, (1, that projects from a sliding bar, 0", supported by the frame 8, and provided with a spring that keeps the rollerp 8o downward with a small pressure. The roller 19 is preferably grooved, so that there will'not be any force to spread the paste, the roller only insuring contact between thepaste-wheel and the folded sheet or signature.

When this pasting apparatus is employed with the Smyth book-sewing machine it is preferable to paste near the back edges of the proper sheets or signatures and upon the surfaces that cometoward the operator, and the go presser bar, which forces the sewed sheets back, is grooved, and acts above and below the line of paste, and does not become soiled with the same.

At one end of the shaft of the paste-wheel a 5 thumb-wheel, 1, should be provided, for rotating the shaft, if necessary, to turn any part of the Wheel that may have become dry down into the paste.

If desired, the shaft and paste-wheel can be revolved by a pulley and belt to pass the sheets through by power, instead of by hand.

We claim as our invention- 1. The combination, with the removable paste box, wheel, and scraper, of a slotted cover, an adjustable gage upon said cover for the folded edge of the signature, and a yielding presser to keep the sheet to the pastewheel, substantially as set forth.

2. The combination, with the paste-box and its cover, of the plate d, books a f, flanges h,

and pin for eonnectin g the box and cover, substantially as set forth.

3. The presser-roller having a grooved periphery, and the gudgeon and its yielding support, in combination with the removable pastebox, the cover, the adjustable gage 12 upon such cover, and the paste wheel within the box, substantially as set forth.
